Southern California -- this just in

An MTV musical coordinator was shot execution-style in the back of the head early Sunday morning in front of his Mid-Wilshire apartment, according to law enforcement sources.

Police detectives believe Gabriel Aron Benmeir, 30, was shot when arrived home around midnight. Several residents reported hearing gunshots at the time but did not report it to police.

A man walking his dog at about 6:30 a.m. found the body of Benmeir, 30, on the sidewalk on Packard Street between Stanley and Spaulding avenues.

The sources, who spoke on the condition of anonymity, said he was discovered face down in a pool of blood. Detective are investigating what kind of weapon was used, but sources said it could have been a shotgun.

There are currently no suspects in the case, the sources said.

Neighbors questioned by police reported hearing a gunshot at about 1 a.m., and police determined the victim lay on the sidewalk for several hours before being discovered.

Benmeir was a resident of the neighborhood who had parked his car and was walking to his home, McAlonis said. Friends of the victim told KTLA News he was in the music industry and did work for MTV. He is listed as a music coordinator and production coordinator on several MTV shows including "Punk'd" and "Top Pop Group."
